-/*----- Revision history --------------------------------------------------*

- * $Log: ectab.h,v $
- * Revision 1.2 2004/04/01 12:50:09 mdw
- * Add cyclic group abstraction, with test code. Separate off exponentation
- * functions for better static linking. Fix a buttload of bugs on the way.
- * Generally ensure that negative exponents do inversion correctly. Add
- * table of standard prime-field subgroups. (Binary field subgroups are
- * currently unimplemented but easy to add if anyone ever finds a good one.)
- *
- * Revision 1.1 2004/03/27 17:54:11 mdw
- * Standard curves and curve checking.
